地图在日常生活中必不可少，但视力受损的用户天生无法使用。它们必须被转录为不可编辑的触觉图形，或者在非常昂贵的形状变化显示器上呈现。为了解决这些问题，我们开发了一个有形的桌面界面，使视障用户能够使用一种名为Tumble Reels的新型物理图标自己构建有形的地图。可伸缩卷轴由吸盘垫组成，确保稳定性，可伸缩卷轴使数字线有形。为了构建地图，音频指令引导用户将Tumble Reels精确地放置在桌子上并在它们之间创建链接。在随后的探索过程中，设备提供用户触摸的点和线的名称。一项预先研究证实，Tibet Reels稳定且易于操作，视障用户可以理解使用它们构建的地图。后续实验验证了所设计的系统，包括非视觉交互，使视障参与者能够快速构建和探索各种复杂的地图。
Maps are essential in everyday life, but inherently inaccessible to visually impaired users. They must be transcribed to non-editable tactile graphics, or rendered on very expensive shape changing displays. To tackle these issues, we developed a tangible tabletop interface that enables visually impaired users to build tangible maps on their own, using a new type of physical icon called Tangible Reels. Tangible Reels are composed of a sucker pad that ensures stability, with a retractable reel that renders digital lines tangible. In order to construct a map, audio instructions guide the user to precisely place Tangible Reels onto the table and create links between them. During subsequent exploration, the device provides the names of the points and lines that the user touches. A pre-study confirmed that Tangible Reels are stable and easy to manipulate, and that visually impaired users can understand maps that are built with them. A follow-up experiment validated that the designed system, including non-visual interactions, enables visually impaired participants to quickly build and explore maps of various complexities.
